(December 18, 2006) CALDICOT, U.K. — With the aim of powering implanted medical devices with “two feet and a heartbeat,” a U.K. industry consortium will develop prototypes — expected in 2007 — for medical devices powered by the human body. The self-energizing implantable medical micro-system (SIMM) project, with collaboration from the Department of Trade and Industry (DTI), will use microgenerators created as MEMS devices to convert human energy expenditure into electrical power.
